I put together a short factual wikipedia page a few years ago about a martial arts organisation I belong to.
Then somebody with more energy than sense in our organisation decided to edit it to massively big us up, introducing various in-house titles that mean nothing to anybody outside (and not much within) and basically making us sound like a bunch of self aggrandising dickheads.
It was removed completely within the week by somebody within the Wikipedia community. Can't say I blamed them - I decided that life was too short to try again!
